CAP AND TUBE FOR TOOTH PASTE AND THE LIKE Filed April 14, 1928 hi; 2 LPPatented June 3, 1930 i PATENT OFFICE EWAI D ERNEST STURK, OF HOLLYWOOD,CALIFORNIA CA1 AND TUBE FOR TOOTH PASTE AND THE LIKE Application filedApril 14,

This invention relates to closures for collapsible tubes for tooth pasteand the like, and has for one of its jects to provide a novel, simpleand inexpensive device of this character which cannot be removed fromthe tube and become lost, which may be easily and quickly moved intoopened or closed position, which will when in closed position preventtheentrance of air into the tube, and

which when in opened position will permit the tooth paste or the like tobe expelled from the tube easily and in a convenient manner.

With the foregoin and other objects in view, the nature of w ich willappear as the description proceeds, the invention consists in the novelconstruction, combination and arrangement of parts hereinafter fullydescribed and claimed, and illustrated in the accompanying drawing,wherein: V

Figure 1 is a view 1n side elevation of a collapsible tube equipped witha closure constructed in accordance with my invention,

Figure 2 is a top plan view of the tube 2 and closure,

Figure 3 is a sectional view taken on the vertical plane indicated bythe line 33 of Figure 1,

Figure 4 is a top plan view of the tube with the closure removed,

Fi ure 5 is a detail perspective view of the c osure, a portion of theclosure being in vertical section, and

Figure 6 is a view similar to Figure 3 illustrating a slightly modifiedform of the invention.

Referring in detail to the drawing, 1 designates the body, 2 the neckand 3 the closure of the tube.

The closure 3 is in the form of a conical cap, and the upper end portionof the neck 2 is of conical formation to provide a seat 4 for the cap.The neck 2 is provided at the base of the seat 4 with an outer annularrib 5. The neck 2 may be solid, as shown in Figures 1 to 5, or hollow,as shown in Figure 6. When of solid construction, the neck 2 is providedwith an angular discharge passage 6 which opens out through the side ofthe seat 4. When the neck is of hollow construcwas. Serial No. 269,996.

tion, the seat 4 is provided with a discharge port 7. 1

The cap 3 is rotatably arranged on the seat 4, and it is heldin place byan annular flange 8 which extends downwardly from its base and surroundsthe rib 5 and which has its lower portion cut as at 9, and bent intocontact with the under side of the rib. The

cap 3 is provided in its side with an opening 10 which when the cap isin opened position 00 registers with the discharge end of the passage 6or with the port 7 depending upon whether the neck 2 of the tube ishollow or solid. When the cap 3 is in closed position the opening 10 isout of registration with the passage 6 or port 7. To permit it to beeasily moved from one of its positions to the other, the cap 3 isprovided at its base with a milled annular rib 11 adapted to be engagedbetween the fingers. To limit "the 70 movement of-the cap in oppositedirections and thus insure its being moved into its fully closed orfully opened osition, means, consisting of a rib 12 carried by the capand a short groove 13 formed in the seat 4 for the reception of the rib,are provided.

The formation of the cap 3 and the seat 4 permit these parts to contactin a manner to prevent the entrance of air into the tube and theformation of these parts and the 10- so cation of the discharge opening10 within the side of the cap to permit the tooth paste to be applied toa brush in the most convenient manner and permit the closing of the capand the application of the paste to the I tooth brush without waste.

Changes in details may be made without departing from the spirit or thescope of the invention as claimed.

What I claim as new is:

A collapsible tube embodyin a conical head having an opening in its 'sie communicating with the interior of the tube and with acircumferentially extending groove in the head spaced from the opening,a neck under- 95 lying and of less diameter than the head and separatedtherefrom by a cylindrical part, said cone, neck, and cylindrical partbeing coaxial, a cap fitting upon the cone and having a port properlypositioned to register 00 with the opening, a cylindrical part having aknurled band as an exterior and fitting upon the cylindrical head, a.flange extending below the cylindrical part and bent inwardly toward theneck, and an inwardly upset part of the cap engaging in the groove andlimiting rotary movement of the cap to proper re 'stration.

n testimony whereof I aflix'my signature.

EWALD ERNEST STURK.
